Abstract
A video apparatus includes a video processor for performing video processing to generate normal video data. The video processor includes an on-screen display (OSD) module for selectively generating OSD data that is capable of being mixed into the normal video data. The video apparatus further includes a digital output path including a digital transmitter and an analog output path including a digital-to-analog converter (DAC). The video apparatus is capable of outputting OSD data through an unauthorized output path out of the digital and analog output paths to provide a user with a warning message or an interactive help dialogue.
